How to use
It is straightforward.
You only put 'Qron Calc Macro' on the Confluence standard table, then enter a formula in the macro body.
And also, you can set numeric format, text alignment, and text style optionally.
Notes on editing
When you insert the macro for the first time, it opens in Direct Formula mode.
From the second edit onward, it opens in Table Editor mode.
After you edit the table, changes may take a short time to appear in the Table Editor because Confluence auto-save must complete. If updates don’t show immediately, wait a moment or trigger auto-save by clicking outside the table or using Update/Publish.
Given a formula "sum(a2:b3)" will be displayed like the following.
The top-left corner, including headers, is A1.
